Swiss YoungPhysicists’ Tournament

Welcome to the SYPT 2019

Dear participants, teachers and jurors

Another year, another host. We look forward to organising the Swiss Young Physicists‘ Tournament 2019 at the Fachhochschule Nordwestschweiz (FHNW) in Brugg-Windisch. The FHNW proved to be an excellent venue for the SYPT‘s little sister, the SYNT in 2017, so we are very confident that with its modern infra-structure it will be perfectly suited for the tournament.

Once again we are expecting the impressive number of 25 teams of three students from all across Swit-zerland, the maximum number we can handle. They have all spent a lot of time designing experiments, collecting data and learning about the theory for one of the 17 IYPT problems. They all look forward to presenting their solutions and to trying to qualify for the Swiss IYPT team.

Hosting more than one hundred students, jurors and staff is only possible thanks to the financial contri-butions from our supporters, but also thanks to the voluntary work of many helpers.

It is my great pleasure to welcome you all to an exciting weekend in Brugg-Windisch!

Samuel Byland ([email protected]), President Pro IYPT-CH

IYPT

The International Young Physicists‘ Tournament (IYPT, see www.iypt.org), sometimes also referred to as „Physics World Cup“, is a scientific competition among secondary school students interested in physics. A so-called Physics Fights lines up three teams of five students each. They in turn present and discuss their solutions to one of the problems, criticise the opponent‘s solution and review the performances of the other teams. All three teams get scores from a jury.

The problems are published a year before the tournament. They are chosen such that no single correct solution exists. Each presentation will show different aspects of the problem. Careful preparation and creativity in solutions are as important for creating a good impression, as are correct school physics and mathematics.

In preparing for the IYPT students do not just learn how to tackle difficult physics problems, but also how to work in a team, use computers to collect and analyse data, present scientific results and debate. The Physics Fights are in English, helping the students prepare for their future at university where an increa-sing number of lectures and seminars are held in English.

Pro IYPT-CH

The aim of Pro IYPT-CH is that of making the idea behind the IYPT better known in Switzerland. It provi-des support for students and teachers in preparing problems and organises the selection of the Swiss team for the international tournament.

Since the first participation of Switzerland in the IYPT (2002) the number of students, teachers and schools participating has increased steadily. In 2005 Pro IYPT-CH organised the International Young Phy-sicists‘ Tournament in Switzerland (Winterthur). This will be the eighth national tournament modelled on the international archetype.

If you would like to support Pro IYPT-CH and the SYPT and would like to be informed about our activities, you are very welcome to become a member. We also appreciate the help of former participants during the preparation for the SYPT and IYPT. Please contact Lioba Heimbach (see below) to get more informati-on about membership or register online (www.sypt.ch).

Problems for the SYPT 2019

1. Invent Yourself: Build a simple motor whose propulsion is based on corona discharge. Investigate how the rotor’s motion depends on relevant parameters and optimize your design for maximum speed at a fixed input voltage.

2. Aerosol: When water flows through a small aperture, an aerosol may be formed. Investigate the parameters that determi-ne whether an aerosol is formed rather than a jet for example. What are the properties of the aerosol?

3. Undertone Sound: Allow a tuning fork or another simple oscillator to vibrate against a sheet of paper with a weak contact between them. The frequency of the resulting sound can have a lower frequency than the tuning fork’s fundamental fre-quency. Investigate this phenomenon.

4. Funnel and Ball: A light ball (e.g. ping-pong ball) can be picked up with a funnel by blowing air through it. Explain the phenomenon and investigate the relevant parameters.

5. Filling Up a Bottle: When a vertical water jet enters a bottle, sound may be produced, and, as the bottle is filled up, the properties of the sound may change. Investigate how relevant parameters of the system such as speed and dimensions of the jet, size and shape of the bottle or water temperature affect the sound.

6. Hurricane Balls: Two steel balls that are joined together can be spun at incredibly high frequency by first spinning them by hand and then blowing on them through a tube, e.g. a drinking straw. Explain and investigate this phenomenon.

7. Loud Voice: A simple cone-shaped or horn-shaped object can be used to optimise the transfer of the human voice to a remote listener. Investigate how the resulting acoustic output depends on relevant parameters such as the shape, size, and material of the cone.

8. Sci-Fi Sound: Tapping a helical spring can make a sound like a “laser shot” in a science-fiction movie. Investigate and explain this phenomenon.

9. Soy Sauce Optics: Using a laser beam passing through a thin layer (about 200 µm) of soy sauce the thermal lens effect can be observed. Investigate this phenomenon.

10. Suspended Water Wheel: Carefully place a light object, such as a Styrofoam disk, near the edge of a water jet aiming up-wards. Under certain conditions, the object will start to spin while being suspended. Investigate this phenomenon and its stability to external perturbations.

11. Flat Self-Assembly: Put a number of identical hard regular-shaped particles in a flat layer on top of a vibrating plate. De-pending on the number of particles per unit area, they may or may not form an ordered crystal-like structure. Investigate the phenomenon.

12. Gyroscope Teslameter: A spinning gyroscope made from a conducting, but nonferromagnetic material slows down when placed in a magnetic field. Investigate how the deceleration depends on relevant parameters.

13. Moiré Thread Counter: When a pattern of closely spaced non-intersecting lines (with transparent gaps in between) is overlaid on a piece of woven fabric, characteristic moiré fringes may be observed. Design an overlay that allows you to measure the thread count of the fabric. Determine the accuracy for simple fabrics (e.g. linen) and investigate if the method is reliable for more complex fabrics (e.g. denim or Oxford cloth).

14. Looping Pendulum: Connect two loads, one heavy and one light, with a string over a horizontal rod and lift up the heavy load by pulling down the light one. Release the light load and it will sweep around the rod, keeping the heavy load from falling to the ground. Investigate this phenomenon.

15. Newton‘s Cradle: The oscillations of a Newton’s cradle will gradually decay until the spheres come to rest. Investigate how the rate of decay of a Newton’s cradle depends on relevant parameters such as the number, material, and alignment of the spheres.

16. Sinking Bubbles: When a container of liquid (e.g. water) oscillates vertically, it is possible that bubbles in the liquid move downwards instead of rising. Investigate this phenomenon.

17. Popsicle Chain Reaction: Wooden popsicle sticks can be joined together by slightly bending each of them so that they interlock in a so-called “cobra weave” chain. When such a chain has one of its ends released, the sticks rapidly dislodge, and a wave front travels along the chain. Investigate the phenomenon.

Regulations for the SYPT 2019

1. Swiss Young Physicists’ Tournament

The Swiss Young Physicists’ Tournament (SYPT) is a physics competition for students in secondary school. Participants are chal-lenged to prepare a theoretical and experimental solution to a complex problem and to present and defend their solution in a debate (Physics Fight) against the opposing team‘s scrutiny.

The SYPT takes place on two consecutive days (e.g. Saturday and Sunday) before the International Young Physicists‘ Tourna-ment (IYPT) of the same year (i.e. usually between March and May). The tournament is organised by the association Pro IYPT-CH.

In order to facilitate preparation for students wishing to participate at the SYPT, Pro IYPT-CH organises the SYPT Physics Week. The SYPT Physics Week is a week-long preparation course during which participants can conduct measurements and learn the basic skills required at the SYPT.

The problems for the SYPT are identical to the ones at the IYPT. However, due to organisational reasons, Pro IYPT-CH may offer preparation courses only to a selection of the problems during the SYPT Physics Week. The problems are published online on www.iypt.org and on www.sypt.ch at least four months before the SYPT.

2. Website

Important information (deadlines, problems, results, etc.) about the SYPT and the Swiss team at the IYPT are published on the SYPT website (www.sypt.ch).

3. Preregistration and Application

The deadline for registration is 9 December 2018. This date applies both for students wishing to participate at the SYPT and the SYPT Physics Week as well as for students who only wish to participate at the SYPT.

An application is only valid if the terms of participation arrive on time and with the respective signatures. The terms of partici-pation can be found on www.sypt.ch.

There are two possible ways to apply. In any case the deadline mentioned above apply:

� School teams: Any secondary school (including international schools, private schools and others) in Switzerland can nominate one or several teams of three students. As an exception the organiser may allow teams of two or four students.

� Individual participants: The organiser will try to match students applying as individuals with other students to form teams of three students.

Each student in a team has to present the solution to a different problem.

4. Fees

The participation at the SYPT and SYPT physics week is free. The costs for train tickets (half-fare), food and, if necessary, accom-modation are covered by the organiser and/or the host in accordance with the “Spesenreglement” of Pro IYPT-CH. Pro IYPT-CH has a limited budget for experimental equipment. Please contact the president in due time if you would like to benefit from financial support. The exact procedure is defined by the “Beschaffungsreglement” of Pro IYPT-CH.

5. Preparation

Pro IYPT-CH seeks the support of universities and research institutes (e.g. ETH, Empa, etc.) in order to allow the students to use adequate experimental equipment where the schools cannot provide this or to get in contact with experts in the respective field. In addition, Pro IYPT-CH organises the SYPT Physics Week during which students receive coaching and can prepare for

11



the tournament.

6. Fight Plan

All teams participate in three rounds of preliminary Physics Fights. The fight plan is published two weeks before the start of the SYPT. Each student in a team takes the role of Reporter, Opponent and Reviewer exactly once. The Physics Fights are in English. In justified cases the organiser may allow exceptions.

7. Physics Fight regulations

7.1. Stages and Time Schedule

At the start of a round the jury members and the teams briefly introduce themselves.

A Physics Fight with three teams is divided into three stages. In each stage the roles of the Reporter, Opponent and Reviewer are assigned according to the table below. If there are teams with more or less than three students or Physics Fights with more or less than three teams, similar schemes apply.

Physics Fight with three teams

Stage 1 2 3

Team 1 Rep Rev Opp

Team 2 Opp Rep Rev

Team 3 Rev Opp Rep

12



The tasks for the three students actively involved in a fight are as follows:

� The Reporter presents his/her solution for the selected problem. The solution is expected to cover at least an important aspect of the problem with a theoretical model and experimental results verifying this model. The solution should be understandable for a secondary school student.

� The Opponent asks clarifying and critical questions and points out possible shortcomings and mistakes in the solution presented by the Reporter. He/She shows the presentation‘s strengths and weaknesses. The discussion has to be based on the solution presented by the Reporter (not on the Opponent‘s). A good Opponent should lead the discussion in a way that both participants can learn something new.

� The Reviewer comments on the performances of both Reporter and Opponent.

The Physics Fight follows a strict timetable (see table below). After the time reserved for a phase has been used up no new thought may be added. If the preparation time is exceeded, the time for the next phase is shortened accordingly.

Phase Time (total 45‘)

Presentation of the Reporter 12‘

Clarifying questions of the Opponent to the Reporter 2‘

Preparation of the Opponent 3‘

Review of the presentation (maximum 5‘) and discussion between Opponent and Reporter 11‘

Summary of the discussion by the Opponent 1‘

Questions of the Reviewer to the Reporter and the Opponent 3‘

Preparation of the Reviewer 2‘

Review of the performances of the Reporter and the Opponent by the Reviewer 4‘

Concluding remarks of the Reporter 2‘

Questions of the jury to all three teams 5‘

7.2. Team work and aids

During a Physics Fight the team members are allowed to communicate with each other. Support from outside the team (e.g. from their physics teacher) is strictly forbidden. The use of internet during a fight is strictly forbidden.

During each stage of a Physics Fight there is only one active participant per team. The other team members are allowed to help with short comments or give technical support.

8. Jury

The Jury is organised by Pro IYPT-CH. There are at least three jurors in each Physics Fight of which one acts as chairperson and ensures that the SYPT regulations are obeyed.

At the end of each stage the jury assesses the performances and every juror shows marks from 1 to 10 for each of the teams in-volved in the stage. The score for a team corresponds to the weighted average (highest and lowest mark with 50 %, all others with 100 %) multiplied by 3 (Reporter), 2 (Opponent) and 1 (Reviewer).

9. Ranking

The grades of each fight are used to make a team and an individual ranking. Both rankings will be published.

13



10. Final Fight

The three teams with the highest total score after three rounds qualify for the Final Fight. In case of two teams in third place with the same total score the more balanced individual scores are preferred. In the Final Fight the third team after three rounds presents first, the first team last.

Within thirty minutes after announcing the participants of the Final Fight, the teams notify the organiser of their favourite problem. If two teams intend to present the same problem, the better-placed team has higher priority. The accepted problems are announced immediately.

The Final Fight follows the same regulations as the normal Physics Fights. Each team member has to be on stage in at least one role. In a team of two the reporter may be on stage only once.

11. Team Qualification

The organiser (in cooperation with the jury) invites up to nine (in exceptional cases ten) participants (SYPT champion and up to six or seven more) for the team qualification where the Swiss team for the IYPT is selected.

Only participants in the individual ranking (see point 12) are eligible to participate at the team qualification.

12. Absence of a team member

In case one or more team members are unexpectedly unable to attend a Physics Fight, the team must inform the organisers immediately.

The team is expected to perform the roles of the missing team members. The grades the remaining team members receive in these stages count as follows:

• The grades in the opposition count 25% and the grades in the review count 50% for the team ranking. The gra-des in the report do not count for the team ranking.

• The other fractions (75% opposition, 50% review) are made up out of the average grades the present team mem-bers received in their originally planned stage. The weighted average of these marks is then counted as the final grade for the team ranking.

• The grades in these stages do not influence the individual ranking.

In case a team is reduced to only one team member, the remaining team member may find one additional helper who is eligi-ble to participate at the SYPT and is not active in another fight. The helper is not allowed to take a role on stage. The organisers then must be informed immediately.

A participant must perform at least one report and one opposition in the three preliminary physics fights in order to be ranked in the individual ranking.

13. Disciplinary action and Violations of Regulations

Participants or teams that violate the SYPT regulations can be sanctioned by a point deduction of up to 10 points per partici-pant or disqualification.

All participants must behave in an appropriate manner. Unfair behaviour can lead to point deduction of up to 10 points per participant or disqualification.

The final decision on any possible sanctions is taken by Pro IYPT-CH.

14



14. Appeal

In case one or several participant or juror feels an action or behaviour of an individual or group does not comply with the SYPT regulations, he or she may choose to report this. The procedure is as follows:

For incidents not concerning grading:

• For incidents occurring during a Physics Fight: The incident must first be reported to the chair of the jury. In case the matter cannot be resolved, the incident may be reported to the organisers. Pro IYPT-CH will decide on further actions or consequences.

• For other incidents: The incident must be reported to the organisers. Pro IYPT-CH will decide on further actions or consequences.

For incidents concerning grading:

• The incident must be reported to the organisers no later than one hour after the respective fight round has finished. The report must include a justification why the grading should be reconsidered. Pro IYPT-CH will then make a final decision. Pro IYPT-CH will in any case justify its decision towards the involved parties.

Note: A retrospective change of a grade or its weighting will only be considered in extreme cases. Due to organisational rea-sons any change of grades will only influence the individual ranking.

15. Responsibilities

The regulations have been approved by the association Pro IYPT-CH.

Zurich, 14/12/2016

15



Ranking, Team Qualification and Awards

In addition to the team ranking, a ranking of the scores of all participants (individual ranking) is publis-hed. The latter is based on the weighted sum of all individual scores in the first three rounds.

The team with the highest score in the Final Fight wins the SYPT Team Competition.

Nine participants qualify for the IYPT team qualification. They are selected by Pro IYPT-CH (in cooperation with the jury) based on their skills shown during the physics fights. Students participating in the team qualification have to prepare a second problem and participate in the team qualification event (MNG Rämibühl Zürich, 5/6 May 2019).

All participants receive a certificate confirming their successful participation at the SYPT, and a small gift. The final teams and up to five additional teams will be awarded with medals and attractive prices.

Rankings are published on www.sypt.ch.
